The volatile composition of musts from different geographical areas within the Rías Baixas Denomination of Origin is reported. Volatile compounds were identified and quantified by gas chromatography/mass spectrometry. The results demonstrate that the Albariño must from O Rosal should be the most aromatic must since it had a significantly higher volatile compound content, and was comprised of the largest group of bound compounds. Non-terpenyl compounds were the most abundant compounds in the Albariño musts for the three geographical areas.
